I like that better than creating the whole HTML in S-Expressions, but at the moment I wonder if the best approach would not be the one I know from XMLC: just operate on the dom-tree of the web page, and then serialize the dom?
Where are good places on the web to discuss such things?
Other features of BRL could be implemented in a non-sexpr language. It just seems nobody cares to make languages truly suitable for database-driven web apps. PHP could have done something like define-input to solve their register_globals problem while retaining a lot of the convenience it had become famous for. A ResultSet object in any language could be extended to have a very useful subset of the functionality in BRL's sql-repeat.
Anyway, I'm not sure the best place for discussion. Most lispers and schemers don't seem interested in web development. Maybe you could discuss it here on news.yc.
